Specification of Letters Patent.

Patented Sept. *7, 1915.

Application filed September 16, 1914:. Serial No. 862,098.

the accompanying drawing, is a specification, like characters on the drawing repre senting like parts.

This invention consists of ,a novel construction of a binding machine.

An object of this invention is to provide a power machine for securely and rapidly ai'iixing metal binding to sheet material whereby the edges of such material, as for example, card-board, paste-board or fiberboard, are protected. The metal binding employed is substantially lJ-shaped 1n section and is applied to patterns and sheet forms or models such as are used in marking but the material for cutting or in cutting out the material directly by passing a cutting edge around the pattern or form superposed upon the material.

Another object is to produce such a machine whereby both hands of the operative are free for the expeditious and facile ma nipulation of the material to which the edging is being applied;

Another object is to provide such a machine with a continuously and power driven cutter whereby the metal binding may be quickly cut or notched to attain flexibility at points where the binding is to be aiiixed to angles in the patterns.

Another object is to provide such a highspeed binding machine with variable speed gearing whereby the speed of the feed and pressure rolls may be easily retarded when the binding is being applied to the patterns at angles.

A further object is to provide in such a machine means whereby the pattern and binding partially attached thereto may be expeditiously and accurately positioned under the rapidly functioning notching means in order that the binding may be notched with exactitude at a point opposite an angle in the pattern.

It is a further object to provide such positioning means that in the hands of an unskilled operative the notch will be cut in the binding with rapidity and unerring precision.

Another object is to provide guiding and positioning means adjacent the notching element whereby when the partially attached binding is to be notched opposite an angle in a pattern the binding will be but slightly separated from the pattern and the pattern edge will be afforded a straight guide from the point of attachment of the binding to such pattern angle and the binding afiorded a straight line from such point to the center or apex of the notching tooth whereby the notch must be cut precisely 0pposite such angle in the pattern edge.

In order to afford an understanding of this invention, a selected embodiment has been illustrated in the accompanying drawings and will now be described.

Fig. 12 is a plan view of a section of the binding as notched by the cutting member.

In this selected embodiment, the power binding machine is shown with a base 1 secured to a suitable support where it may be conveniently operated, as for example, a bench 2. An integrally cast frame 3 is affixed to the base 1. The frame comprises a gear and shaft-bearing housing 4, at its power end, and four arms laterally projecting therefrom which terminate respectively, at the work end of the frame, in the cutting member, the upper feed and pressure roller, the lower feed and pressure roller, and the means for elevating such lower roller.

A belt 5 leads from suitable power means to a pulley 6 secured by a set screw 7 to the end of the machine power shaft 8 which has its bearing in the frame.

Tn the form illustrated the speed of the pulley and hence of the main power shaft is controlled by means of the brake shaft 9 which is screw-threadedat its point of support 10 in the frame and carries at its end near the pulley an arm 11 normal to the brake shaft upon which is secured an idler 12 adapted to bear against the belt 5 to prevent slippage between the belt and pulley 6. The end of the brake shaft terminates in a friction member which consists of a fiber washer screwed into a recess in the end of the brake shaft, the screw-head being countersunk below the level of the washer, The washer is adapted to bear forcibly against the inner face of the pulley near its periphery. The opposite end of the brake shaft has secured thereto crank 14: and its handle 15. The screw threads in the brake shaft hearing are such that when the handle is lowered by being pushed away from the frame the shaft will be forced nearer the pulley, the fiber washer will engage the inner face of the pulley, and the idler 12 will co-incidentally be removed from contact with the belt. The belt, being loose, will slip on the pulley which will be retarded to a greater or less degree accordingly as the handle 15 is pushed farther away from the frame, and the friction men.- ber the more forcibly pressed against the pulley face. A screw 16 is screwed into a threaded recess in the frame beneath the brake shaft and forces a brass pin against the shaft opposing, but not preventing, rotary movement thereof, and overcomes the rotative tendency of the shaft when the idler is bearing upon the belt.

The main driving shaft has integral therewith a worm 17 which engages the gear 18 fastened to the upper feed and pressure shaft 19. -Mounted upon this shaft 19 and revoluble therewith is the smaller gear 20 which meshes with the twin gear 21 mounted upon the lower feed and pressure shaft 22 so that these two shafts, which carry at their work ends the feed and pressure rollers, will be revolubly actuated in opposite directions and at the same rate of speed and will thus feed forward the material placed therebetween.

The uppermost or cutter shaft 23 has mounted thereon, at the power end, a pinion shown in dotted lines in Fig. 2, which meshes with the gear 24, mounted on the stud shaft 25. The cutter shaft 28 termie nates in an end bearing cap 26. The pinion 27 is concentrically superposed upon the gear 24 and secured to the stud shaft 25. This pinion meshes with the gear 20. This cutter shaft 23 is thus rotated at a higher half to one has been found eflicient.

rate of speed than that of the feed rollers in practice, a speed ratio of five and one The gear 18, secured to the shaft 19 by a suitable set screw shown in Fig. 1, has countersunk on its rear face a steel bearing plate 28, see 2, which offers a bearing to the power ends of the shafts 22 and 23 and the cap 26 of the cutter shaft, thus preventing any possible lateral thrust. The three shafts have suitable supports in the frame and frame arms.

The upper feed and pressure shaft 19, at its work end, extends through the casing arm and carries keyed thereto the upper feed andpressure roller 29 and the retaining screw 30. The peripheries of these twin rolls 29 and 31 are beveled so that the greatest diameters are opposed and are somewhat back of their front faces.

The casing arm carrying the lower feed and pressure shaft 22 at the work end is reduced and has slidably mounted thereon a sleeve 32 to which is secured a handle for pushing the same inwardly against the,

action of a spring washer 33. The sleeve is secured against rotation by means of a lug projecting from the casing and engaging a guideway in the sleeve. The sleeve 84, mounted on the reduced casing arm and carrying at its front end and next'to the lower feed and pressure roller the different sized rear rollers and the fin back guide 45, is adjacent the sleeve 32 and normally bears thereagainst. This roller sleeve is secured against rotation by means of a lug on the rear sleeve, which selectively engages in slots or guideways 35 in the roller sleeve, a slot being opposite each roller and the fin at. The casing arm has an end opening for the lower feed and pressure shaft 22 whereby the shaft may be moved in a vertical plane permitting the two pressure rollers to be moved apart while the machine is running, to facilitate the rapid removal of the material when an angle requires a notch to be cut in the binding. The guide 7 5, shown in dotted lines in Fig. 5, provides a vertically movable bearing for the shaft 22. A vertical way 76 shown in dotted lines in Fig. 1 for this cylindrical guide 7 5 is cut in i the lowest arm of the frame and extends upwardly adjacent the top of the frame arm containing the lower roller shaft. The guide 75 is centrally bored near its upper end and provides a bearing for the shaft 22 at the work end and effectively prevents lateral play of the shaft. The lower feed and pressure roller is keyed to the shaft 22 immediately beneath the upper feed and pressure roller, and has a broadfiange at its outer end on which is rotatably mounted a bearing washer 36.

The stud shaft 37 projects from the lowest arm of the casing. This stud is secured against rotation by means of the locking screw 38 in the casing frame. The stud shaft terminates in an enlarged head which forms a countersunk detent for the hoist and retainer 39. The hoist 39 is revolubly mounted on the stud, its periphery being beveled inwardly so that it may engage the bearing washer 36 but not the feed and pressure roller. The hoist 39 has a narrow flange l0 which bears against and retains the washer. The washer 36 normally rests in a concave surface 4-1 out into the periphery of the hoist 39, corresponding substan tially to a sector of the circumference of the washer. In this position the feed and pressure rollers are spaced apartand the pattern and binding may be easily placed therebetween. Means are provided whereby this guide may be rotated a distance sufficient to cause the washer bearing 36 to rise from the cavity to the periphery of the hoist, thus causing the lower roller shaft to be elevated and its roller 31 and rear rollers on the sleeve 34 to be brought into the efiicient operating distance from. the upper roller as shown in Fig. 5. The hoist is rotated through a small are by means of a rod 42 eccentrically affixed thereto. A slot is cut in the periphery of the hoist adjacent the concave surface, and the rod 42 secured therein. The rod extends downwardly through the bench and terminates in a pedal on the floor by which means the rod may be pulled downwardly against the tension of the helical spring 43' placed thereon and positioned between the top of the bench and the nut 4a.

In order to secure the requisite degree of flexibility in the binding when affixing the same to a sharp angled edge, it is neces sary to notch or cut out a small section of the sides of the il-shaped binding. This is the function of the cutting member secured to the work end of the topmost shaft.

The cutter shaft armof the frame has a reduced portion at its end and mounted thereon is the washer 46 and the sleeve T7, the latter being centrally bored to fit the reduction and is secured against movement thereon by means of the screw 48. The sleeve 47 has a vertical slot 49 therein, in which is positioned the die block 50. The die block has a bearing face 51 with a circular hole therein, in which the reduced end 52 of the cutter shaft rotates. The shaft end bears an eccentric stud 53 upon which is placed a roller washer 5%. The die block has a flange 55 which is cut away at 56 to allow full play to the Washer 54 on the eccentric stud.

The cutter 57 has a transverse slot 58 of a width substantially equal to the diameter of the external edge of the washer 54:. The edge 59 of the cutter adjacent the flanged side of the die block is beveled, leaving the double-edged tooth 60. The die block at its upper end has an opening cut therethrough to form shearing edges to cooperate with the cutting edges of the tooth 60. This cut is made at an angle to the die block flange 5 and forms, at the baclr of the die block, a beveled or sloping channel 70, as shown in dotted lines in Fig. 9, providing a guideway for the metal edging.

The cutter 57 is positioned against the flange and the bearing face 51 of the die blocl: and the roller washer on the eccentric stud 53 engages the transverse slot 58 of the cutter. Thus, the rotation of the cutter shaft, bymeans of its eccentric stud, imparts to the cutter a limited, verticallyreciprocating andsliding movement. The tooth 60 is of such height that when midway its stroke, it will be positioned in the center of the pathway formed by the flange opening and channel. '50 and the U-shaped bindmay slide therethrough, its two flanges passing, the one above the tooth and. the other below. The edge 61 of the die block flange and the edge 62 of the die block form,

on the descent of the tooth 60, the shearing edges for the lower cutting edges of the triangular tooth; on its ascent, the upper edge 63 of the fiange'and the upper edge (i l of the die block form the shearing edges for tile upper cutting edges of the tooth. The vertical movement of the tooth is limited in such manner that it is impossible for the tooth to slide above or below the channel, leaving it completely open, and hence the metal binding can only enter the path of the tooth when the tooth is midway and when the binding flanges are placed on either side thereofin operative or cutting position. Tn this selected embodiment, the upper shearing edge 64c is out about a sixtyfourth of an inch above the plane of th upper flange shearing edge 63 while the lower shearing edge 62 is out about a sixtyfourth of an inch below the plane of the lower flange shearing edge 61. The two corresponding opposed faces of the channel are likewise cut away. Thus, when the binding is out; as shown in Fig. 12, the vertically opposed edges 77 and '28 are both outwardly bent from the normal line of the flanges of the binding- The upper edge 77, when the binding is passed through the rollers, overlaps to edge 79 while the lower edge 78 overlaps the edge 80, forming a doubl retentive and reinforced angle binding.

The face of the cutter opposite the tooth has a recess, shown by dotted lines in Fig. 10, which extends vertically downward this cutter face to a point substantially below beveled tooth bearing edge 59 of the .cutter, a false flange 69 Whose faces are parallel. This angular recess serves to guide the positioning of the pattern so that the metal binding attached thereto and projecting through the cut in the fiange of the die block and passing in the pathof the tooth, will be notched or cut at the exact point opposite the angle in the pattern. The beveled edge of the cutter above the tooth forms, in combination with the flange of the die block, a triangular channel 72 through which the metal cut is pushed upwardly and drops away. A similar channel is likewise formed below the tooth by the beveled edge 59 of the cutter and the flange, thus furnishing an outlet for the triangular piece of m tal cut on the downward stroke of the cutter.

The block cap 73 has a vertical slot, forming, with the slot 49 in the sleeve 4E7, a reccss in which the cutter and die block are positioned, the side of the slot and the flange and bearing face of the die block forming way in which the cutter may slide in its reciprocating movement. The cap 73 is se cured to the sleeve 4-7 by the screws 64 which engage in the threaded holes 65 in the sleeve. The cutter is held against lateral movement by the flange 55 of the die block and is pressed thereagainst and wear taken up by the brass pin inserted in the threaded aperture in the side of the cap which pin is adjustably pressed against the cutter by means of the screw 67. A similar brass pin and screw .66 inserted in the side of the cap, and bearing. against the cutters edge, posi tions it against the bearing face of the die block and takes up wear.

The thin metal blade or tapered fin 68 is affixed to and projects vertically from the flat top surface of the cap. Tts inner vertical edge is beveled and forms a flush continuation of the false flange 69. The outer face of the tapered fin thus forms an extension of the short side 7% of the obtuse-angled recess in the cutter while its inner face forms in combination with the beveled tooth-bearing edge of the cutter. and the sloping channel 70 of the die block, a

straight guideway to direct the metal edging into and past the path of the cutting tooth. In that it is essential to the accurate notching of the binding that the pattern edge and the flanged binding remain close together and as the fin functions to separate the binding from the pattern and to guide the binding to the cutter, the tapered fin is made extremely thin, and the pattern and binding are thus but slightly separated when the binding is notched. There is thus provided a construction whereby a pattern may be quickly and easily positioned and a notch cut in the metal binding at a definite and precise point with relation to the pattern. The junction of the two faces or sides of the obtuse-angled recess forms a guideline or index 71 for the accurate positioning of the pattern therein which is continuously and unalterably in perfect alinement with the apex of the angled notching tooth.

In the operation of this machine, the pattern with the U-shaped metal binding positioned on its edge is placed between the rollers 19 and 31 and the back of the bind ing is placed against the rear roller desired. If a straight edge is being bound, the large rear roller is brought into position as a back guide therefor by rotating the sleeve 34 until the slot corresponding thereto is engaged by the lug on the rear sleeve. The smaller rollers are so positioned for curves of shorter radii. The small fin 15 is employed in applying the metal binding to the smallest curves and to sharp angles in the patternnotably sharp reentrant curves, slots and angles. The power having been turned on, the machine started, and the proper rear guide positioned, the operative presses down the pedal after positioning the material. The pressure on the pedal causes the lower feed and pressure roller to be raised against the tension of the spring 43 into operative position in conjunction with the upper roller. Due to the fact that the rollers revolve at the same rate of speed and in opposite directions, the pattern and binding are automatically fed through while the binding is simultaneously pinched or pressed on the pattern. The point of great est pressure of the rollers, due to their beveled peripheries, is slightly in from the edge of the pattern. A long space has been provided between the two roller shaft bearing arms of the frame in order to facilitate the manipulation of the pattern when the binding' is being applied, especially in affixing the metal strips to the edges of reentrant curves in the patterns.

In order to securely fasten the binding to an angle in the pattern it is essential that the binding be notched. If not so cut, the binding rollers, after passing such a conformation will leave a ridged, or buckled edge or else the flanges of the binding flare outwardly and a loose and irregular pattern edge is produced and the utility of the pattern destroyed. It is to obviate such contingency that the binding is notched. It is further apparent that the notch must be cut in the binding precisely opposite the apex of the angle in the pattern. To achieve this result, the operative, while the feed and pressure rollers are a short distance away from the angle in the pattern, without stopping the machine, takes his foot from the pedal, the lower roller returns to normal depressed position and the ready disengagement of the pattern and binding is permitted. The operative taking the pattern and its partially attached binding in his hand, or handsas both are free 'in this power ma'chinesimply raises them to the adjacent cutter positioned on the upper arm of the machine. The expeditious notching of the binding is efiected by the continuously operating cutter which is geared up in the ratio of approximately five and one half to one. he angle in the pattern is then quickly positioned at the index 71 in the angular recess in the cutter formed by the obtuse angle beveled in the rear face of the toothed reciprocating member. The index as above described, is exactly opposite the apex of the triangular horizontal tooth 60. Forming a prolongation of one side of this obtuse angle is the thin metal blade or tapered fin 68. As the pattern is slid into this angular recess, the blade is interposed between the pattern edge and'the flanged binding separating them but slightly-due to its extreme thinness. The binding is directed in this manner into the guideway leading past the triangular tooth and thus simultaneously with the positioning of the apex of thepattern angle at the index in the cutting member, the binding goes into its guideway and, when the rapidly reciprocating triangular tooth reaches itsvmidway point, the flanges of the binding are snapped by the elasticity of the metal binding into position above and below the tooth whence on its descent a triangular notch is cut in the lower flange and on its ascent a similar notch is cut in the upper flange. The little metal triangles pass out through the upper and lower channels provided therefor. Thus, in this selected embodiment, when the tooth 60 upwardly moves, cooperating with the edge 63 it cuts the binding edge 79 on one side without bending while the other edge of the tooth upwardly bends the binding until co'ciperating with the elevated shearing edge 64: it cuts the binding edge 77 on the other side. Similarly in its descending travel the binding edge 80 is out without bending while the edge 78 is downwardly bent and cut. The sides of the channel guideway leading from the toothed cutter are correspondingly cut away in order that the bent portions may not be again straightened. There is produced a notch with off-set sides whereby when the binding is applied to the pattern angle the overlapping of the two ill-shaped binding flanges produces a tight, durable and smooth edge.

Due to the perfect alin'ement of the apex of the pattern angle, the apex of the obtuseangled recess and the apex of the triangularshaped cutting edges of the tooth, the triangular notches are cut with absolute precision opposite theangle of the pattern. It is readily perceived that at the instant the notching tooth functions, the guiding and positioning elements in conjunction with the notching tooth and the index, substantially form an isosceles triangle. The pattern edge from the point of attachment to the binding thereto along the tapered blade guide to the index opposite the apex of the tooth forms one of the equal sides the binding directed along the face of the tapered blade guide from the point of attachment, to the apex.

of the tooth, forms the other of the equal sides; while the base is a line between the tooth apex and the angle index. It is thus obvious that when the binding is cut, the notch therein must be precisely opposite the angle in the pattern and a perfect junction assured. It is apparent that this construction functions equally well for all angles whose sharpness demands notching in the binding as the index and one side only of the angular recess are employed in accurately positioning the pattern. And, as the distance along the pattern edge from the point at which the binding is aflixed to the index is the same as the distance along the binding from such point to the apex of the triangular notching tooth, the positioning of the apex of an angle in the pattern edge at the index will cause a notch to be out in the binding at the exact point opposite such apex of the pattern angle. The binding having thus been notched, the pattern is placed between the feed and pressure rollers, the operative again places his foot on the pedal whereby the hoist 39 is rotated, the lower roller thereby raised into cooperating position with the upper roller, and the pattern and binding are again automatically fed therebetween and the binding pinched on the pattern. I

In aflixing the binding at angles or around sharp curves it is desirable that the speed of the machine be reduced. This the operative quickly efi'ectuates by pushing outwardly the handle 15 which is placed within easy reach. This movement operates to decrease the pressure of the idler on the belt and to force the friction washeragainst the pulley on the driving shaft whereby the machine functions at retarded speed. The

bindin havin then been secured to the pat-' t? D i Rapidity of operation, a prime factor in work efficiency, is further secured in that both hands of the operative are free for the facile manipulation of the material both in its positioning between the feed and pressure rollers, in its removal and replacement in the high-speed cutter, and .in its return 'andexpeditiously effected; by means of the speed-retarding device, the secure aflixing of the binding tosharp curves and angles in the sheet material is easily accomplished; inshort, this improved high-speed machine, which is adapted to be worked by an unskilled operative, turns out with great rapidity metal-edged patterns which are models of good workmanship and are superior to the product of the old manually operated machine and blind cutter.

17. in a binding notching means, the combination of a die block having a vertical way on one side, a transverse guideway on the other side intersectingsaid vertical'way, a reciprocating cutter adapted to move in said vertical way, transverse shearing edges adapted to cooperate with said cutter, one vertical pair of shearing edges being relatively spaced farthe' apart than the other ver ical pair of shearing edges whereby when a notch is cut in the binding the horizontally opposed sides of said notch will lie in difierent planes.

' 18. In a binding notching means,the combination of a cutting element and means cooperating therewith to cause the binding to be notched and the binding flanges on one side of said notch to be bent respectively above and below the corresponding sides of said binding on the other side of said notch. 19. A die block having onone side a plane face, a flange on said face, a guidewayformed by a transverse cut 1n said flange and Saul plane face at thelr lntersection,"

upper and lower shearing edges in said exactly opposite theguideway on said flange and on said plane face at their intersection, said upper plane face shearing edge being above the line of said upper flange shearing edge said lower plane face shearing edge being below the line of said lower flange shearing edge, and a reciprocating cutter adapted to cooperate with said shearing edges whereby when the binding is notched the binding flanges on one side of the notch will be bent respectively above and below the corresponding sides of said binding on the other side of said notch.

20. A die plate having a bearing face, a relatively narrow flange at one edge thereof, a reciprocating cutting element slidably mounted on said face, said die plate and flange being constructed to permit a pattern and partially attached binding to be introduced to said cutting element without being separated by said die plate.

21. A die plate, having a bearing face, a relatively narrow flange at one edge thereof, a reciprocating cutter slidably mounted on said face, a guideway for a pattern and partially attached binding strip formed by cutting through said die plate at the intersection of said face and said flange and by completely cutting away said flange adjacent said die plate cut whereby said binding and pattern may be introduced to said out ter without being separated by said die plate.

A die plate, having a bearing'face, a relatively narrow flange at one edge thereof, a reciprocating cutter slidably mounted on the said face, a guideway for a pattern and partially attached binding strip formed by cutting through said die plate at theintersection of said face and said flange and by cutting away said flange adjacent said die plate cut, shearing edges formed by said cuts on said die plate and flange at said intersection, and adapted to cooperate with said cutter.

23. In combination with a die plate of the character described, a cutting element comprising a cutter plate adapted to reciprocate on said die plate, a cutting tooth on one edge of said plate formed by beveling said edge whereby when the binding partially attached to a pattern is introduced to said cutting tooth the binding and pattern will be but slightly separated. Y

In a binding notching means, relatively movable male and female cutters adapted to notch the flanges of a pattern binding strip, said cutters being formed to bend the flanges outwardly at one edge of each notch, whereby the edges of the notches may overlap when the strip is bent to form a corner.

25. In a binding notehing means, a female cutter, a reciprocating male cutter, said cutters being adapted cooperatively to cause the flanges of a binding strip to be notched and to bend outwardly at one edge of each notch.

26. In a binding notching means, a cutting element, a member cooperating therewith, shearing edges on said member, said shearing edges cooperating with thecutting element to cause the flanges of a binding strip to be cut and to bend outwardly at one edge of each notch.

27 In a binding notching means, a cutting element, a pair of opposed angular shearing edges on said element, two correspondingly opposed sides of said pair of angular edges being ofiset, a relatively movable cutting member, a pair of oppositely facing angular cutting edges on said member, said pairs of shearing edges being adapted to cooperate with said cutting edges to cut angular notches and to bend the flanges of a binding strip outwardly at one side of each notch whereby the edges of the notch may overlap when the strip is bent to form a corner.

28. In a binding notching means, a die plate, a bearing face thereon, a reciprocating cutter slidably mounted on said face, said die plate being cut away to form a passage therethrough to the cutter whereby apattern and partially attached binding may be introduced to the cutter without separation by the die plate.

29. In a binding notching means, a die plate, a bearing face thereon, a reciprocating cutter slidably mounted on said face, a tooth on said cutter, said die plate being cut away to form a passage therethrough to the tooth whereby a pattern and partially attached binding may be introduced to said tooth without separation by the die plate.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
